Verso ignition error

My 2010 Toyota Verso with a gasoline engine is showing an error related to "Terminal 15 ignition positive interrupted". Symptoms are just the error stored in the memory and the engine won't start. Likely cause, according to the diagnostics, is a defective cable or plug connection. Anyone seen this before?

A 2010 Toyota Verso with a gasoline engine is experiencing an ignition error related to "Terminal 15 ignition positive interrupted," preventing the engine from starting. Diagnostics suggest the issue may be due to a defective cable or plug connection. A similar problem was resolved by checking for voltage drops and inspecting connectors, leading to the discovery of a defective connector on the wiring harness, which was repaired at a workshop.

Sounds like a PITA. I had a similar gremlin with my old Vauxhall Astra; turned out to be a corroded wiring harness connector. Do you have a multimeter? Check for voltage drop across the ignition circuit when you try to crank it. Could be a power supply issue or a bad ground. Rule out the easy stuff first like the battery terminal.

Thanks. Where exactly on the ignition circuit did you find the voltage drop on your Astra?

I chased my tail for hours! It ended up being a connector near the starter motor. Honestly, unless you're comfortable probing around the electrical system, I'd take it to a workshop. Could save you a lot of grief.

Thanks for the suggestion. I took it to the workshop, and it was indeed a defective connector on the wiring harness. Repair cost 95€ Appreciate the help.
